Abstract
Greases are a type of lubricant that has higher viscosity. Manufacturing greases are conducted by mixing
base oils with calcium, sodium, or lithium mineral salts. Manufacturing process is complex and changes in
parameters results significant change in Grease properties. The increase in mineral salts costs and their effect on
nature caused researchers to look for alternative materials that can replace mineral salts. A novel method for
manufacturing grease is to use polymers as thickener agents. In this study, 12% polypropylene was used to produce
grease from poly alpha olefin. In order to increase grease’s high-pressure properties, 2% hexagonal boron nitride
was added. Manufactured grease was compared to lithium grease with hexagonal boron nitride addition. Both
samples were tested on ball-on-disc tribometer on mirror polished 4140 and results were discussed.
